Specication oi Letters Patent.

Patented March 2, 1909.

Original application filed February 4, 1908, Serial No. 414,235. Divided and this application filed September 9,

To all whom it may concern:

Be it known that l, JOHN PFEFFER, a citizen of the United States, and a resident of Spokane, in' the county of Spokane and State of l/Vashington, have made certain new and useful Improvements in Bundle-firing Machines, of which the following is a specification.

This invention relates to bundle wiring machines.

rihe present application is a divisional one, the subject-matter being disclosed in a prior application, No. 414,236, filed February 4th, 1908. l

My invention is in the nature of a machine to be used in fastening together by wire, bun dles of small boards, such for instance as are used in making boxes, and for fastening together shingles into bundles, and other similar uses, and it consists in the novel constructions and arrangements herein described and claimed.

An object of my invention is to provide a device which may be used in subjecting a bundle of materials to pressure in order to get the same into a compact condition and to hold it while the binding wire is being applied.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the machine partly in section showing the method of wiring a bundle. Fig. 2 is a front view of the device. Fig. 3 is a detail plan view partly in section of the adjustable arm and clamping mechanism.

Referring now to Fig. 1, M is the main frame, upon the back end of which are erected standards N and N, in which are mounted the journals of the spool K carrying the coil of wire. G and G are upright standards securely fastened to the frame M. An adjustable clamping arm L is arranged for movement up and down between the stand ards G and G, and may be clamped in any position.

The means for clamping the armLis shown in Figs. 1 and 3. y rihe rear end of the arm L is provided with a reduced portion 0, constituting a tongue and arranged to extend between the members G and G. Secured to this tongue O is a rearwardly projecting screw P, bearing thereon a block Q, arranged to be q'forced up into engagement with the rear sides of the upright standards Gby means of a threaded clamping nut R, which is pro- Serial No. 452,186.

videdl with a handle for manipulating the same.

E is a vertically adjustable table having a pendent plate portion e, which extends through the horizontal frame M, the plate e being of the shape of a half moon, about two inches in thickness and one foot long at its longest or upper side, fastened rigidly to the bottom of the table E, and working up and down through a groove in the frame M. The lower round ends of the plate e rest unfastened upon the end of a lever F, fulcrumed at f between upright standards G and G, and the back end of this lever F is connected by a link H to a treadle iever l, whose back end is fulcrumed at i between the downwardly depending supports A secured to the rear end of the frame l/i. The front end of the lever l is fastened to a treadle B, adapted to receive the foot of the operator. The treadle lever l is provided with a tooth t which is ada ted to engage one of a series of ratchet teet i T attached on the inside of the upright standard G, toward the bottom end thereof.

C and C indicate the legs or supports for the device, and D and D longitudinally extending braces therefor.

From the above description of the various parts of the bundling machine, the operation thereof can be readily understood. In the use of the machine a bundle of boards, shown at S, is placed upon the vertically adjustable table E, the upper clamp arm L being adjusted to suit the size 0f the bundle and being clamped iirmly in position by means of the clamping nut R. rlhe operator compresses the bundle to its smallest dimensions by thrusting downwardly upon the treadle B, which, through its connections l, H and F, causes the supporting table E to compress the bundle between such table and the superposed clamped arm ll. 7When thus compressed the treadle lover l is given a lateral motion to cause its tooth t to engage the teeth of the ratchet bar T, and thus hold the bundle under compression while being tied. The wire w is drawn from the reel through the guide loop g at the top of the standards and is extended downward through a hole in the lower jaw of a pair of pincers U, which are made of a particular shape to coperate with the bundle wiring machine and which are fully described in a prior application No. 414,236, filed February 4, 1908, A eretofore-mentionedLThe wire is then lll) drawn in a loop around the bundle to be tied, as indicated by the numbers 2, 3, 4 and 5. rIhe o erator then draws the wire'under Va pin in .t ie pineers and at the Vsame time spring V, which bears upwardly on the lever Ill, causes the table E with its load to descend, thereby permitting the bundle to be easily removed.

It will be seen that I have provided a device which is simple in operation and yet effectually serves the purpose for which it is intended. I desire especially to call attention to the table E with its depending plate e and the manner in which the latter is shifted. It will be seen that owing to the circu lar shape of the bottom of thel plate that there is very little sliding frictional engagement, while at the same time the power is transmitted undiminished in an approximately vertical direction.

I claiml. In a bundle wiring machine, a *frame comprising a pair of upright posts, an arm movable longitudinally of said posts and arranged to be clamped thereto, a table provided with a downwardly depending plate arranged to pass through a slot in the frame, a pivoted lever having one end in normal engagement with said plate, and a treadle for operating the lever.

2. In a bundle wiring machine, a frame provided with horizontal and upright portions, a laterally extending arm arranged to be clamped at various heights along said upright portion, a table provided with a downwardly depending plate arranged to enter a slot in the horizontal portion of' the frame, said plate being provided vwith a circular bottom, a pivoted lever having one end arranged to engage the circular bottom of said plate, and a treadle for operating said lever. Y

3. In a 'bundle wiring machine, a frame comprising two upright standards and a horizontal portion secured thereto, an arm provided with a reduced portion arranged to enter between Vsaid standards and to be clamped at various heights therealong, a movable table provided with a downwardly depending plate having a circular bottom, a pivoted lever arranged to engage the circular bottom of said plato, a link attached to the free end of said lever, and a treadle bar pivotally attached to said link.

4. In a bundle wiring machine, a frame comprising upright portions and a horizontal portion, a reel pivotally mounted between two of said upright portions, an arm provided with a reduced portion arranged to enter between two other upright portions, a clamp for clamping said arm to said upright portions at varying positions therealong, a movable table provided vwith a downwardlyT depending plate, the latter having a rounded. bottom, said plate being adaptedV to enter slot in said horizontal portion ofthe frame and to be guided thereby, a pivoted lever arranged to engage the rounded bottom oll said plate, a treadle lever pivotally attached to said lever, and means for locking said treadle lever in its depressed position.
